What is CVE-2023-2905?

The Mongoose web server, developed by Cesanta, exhibits a heap-based buffer overflow vulnerability in version 7.10 due to inadequate validation of the length of parsed MQTT_CMD_PUBLISH messages with variable-length headers. This flaw, found in the default configuration, could potentially allow attackers to exploit system memory. Users of Mongoose versions prior to 7.10 are not affected, and the issue is addressed in version 7.11. It's crucial for administrators using affected versions to upgrade to ensure system integrity and security.
